Key Features
ARITA S-Pattern (Lift Type) Check Valve
ARITA S-pattern non-return valve is designed to allow flow in one direction and automatically prevent backflow when flow stops. The lift-type disc moves vertically, providing stable closing performance for high-pressure industrial pipelines.
PN40 Pressure Rating
Designed for PN40 nominal pressure, with tested performance suitable for:
40 bar up to 120°C
27 bar up to 300°C
23 bar up to 400°C
Cast Steel Construction (GS-C25)
Body & cover: Cast Steel GS-C25
Seat (DN ≤ 50): Stainless Steel
Seat (DN > 65): Carbon Steel
Spring (up to DN50): Stainless Steel
Spring (from DN65): Alloy Steel
This construction provides high mechanical strength and excellent performance for elevated pressure and temperature service.
S-Pattern Flow Design
The S-shaped internal flow path allows smooth vertical disc movement, making the valve suitable for horizontal pipeline installation where reliable backflow prevention is required.
Flanged End Connection
Flanged ends designed for PN40 piping systems, ensuring secure installation and compatibility with high-pressure industrial pipelines.
DIN Standard Face-to-Face
Manufactured according to DIN 3202, allowing easy replacement and standardised installation.
Applications
Steam and condensate lines
High-pressure water systems
Industrial process pipelines
Power plants and utility services
Chemical and petrochemical plants
Non-aggressive liquids and gases
